Personally, not sure about those studios, not much info/experience of what they have. But sounds to me like a more MP investment and with access to SWWS, Sony Pictures Entertainment / Imageworks library and expertise, and other divisions of Sony they will have their talents nurtured to something bigger and better, hopefully.
I sense smartphone gaming as well, with probably helping existing PS Studios in implementing MP into their already amazing SP games for more longevity and possible monetization like Uncharted 4 MP, which is so much fun and spent lots of hours in it and even money for some cosmetics that you can get for free eventually.
